Amylase / Creatinine Clearance ratio Calculator (FE amylase)

Differential diagnosis of Acute pancreatitis and Macroamylasemia
Amylase Clearance (%) = (Urine Amylase × Serum Cr) ÷ (Serum Amylase × Urine Cr) × 100

Serum Amylase (U/L):
Serum Creatinine (mg/dL):
Urine Amylase (U/L):
Urine Creatinine (mg/dL):

Amylase Clearance ＞ 5% : High probability of Acute pancreatitis (Low probability of Macroamylasemia)
Amylase Clearance ＜ 1% : High probability of Macroamylasemia (Low probability of Acute pancreatitis)
